Duramax stalled and no start

Hero Member

Hey got a 6.6 gmc lily Duramax. 300000 Alison auto. Had a quarter tank but decided to stop at gas station and pop another $20 in. Put my fuel in, and then, an unusual start. Took longer to start. But it did after a couple tries. I drove about 20 ft and it stalled. It just cranked but no start. No rpm on the gauge. I opened the bleed screw on the filter and pumped it about 40 times and got bubbles and diesel. Closed the bleed screw and then tried it. No go. No difference. Codes are PO670, PI404, PO401, PO404, PO405. Although egr was deleted. Must be old codes the egr ones. Checked under hood fuses. All good. Gotta check relays but gotta get it home first. Any help would be appreciated.

Ok. Yes. With how fast these batteries spin the engine, there should be some rpms. Ill go back and check that pump to see what was put in tank. Ill also check out the rag thing. Thanks guys. Ill post back when I get to it.
